The pH Scale is a scale made to show how acidic or alkaline a substance is. The pH of something is measured with pH paper which can vary from wide range paper‚ which covers all ph’s‚ but is not as accurate at some others. There are pH papers that get very specific that can have a range such as 2 or 3 and get much more precise. The neutral on the scale is 7. Anything that is below 7 is considered acidic and anything above 7 is considered alkaline. Acidic substances contain more H+ than OH-. H+

Macromolecular Composition of the Liver Cell Formal Report Aims The aim of the experiment was to test for the presence of DNA‚ RNA‚ protein and glycogen in the cytoplasm and the nucleus of bovine liver cells. From the findings of the results the distribution of these macromolecules can be shown within the liver cell. This was carried out by undertaking qualitative experiments‚ where the observation of a colour change was noted and a quantitative experiment‚ where numerical data was recorded from

Running head: FATTY LIVER DISEASE Fatty Liver Disease Evetta Brown June 08‚ 2011 MA111 Instructor Leila L. Hamka The liver has over 200 functions that it plays. There are over 100 types of liver diseases. Many of these diseases can be life threating if they are not treated correctly. This paper will focus on the fatty liver disease. It will describe the liver‚ discuss the disease known as fatty liver disease‚ alcoholic and non alcoholic‚ give

A pH meter is an electronic instrument used to measure the pH (acidity or alkalinity) of a liquid (though special probes are sometimes used to measure the pH of semi-solid substances). A typical pH meter consists of a special measuring probe (a glass electrode) connected to an electronic meter that measures and displays the pH reading. The probe The pH probe measures pH as the activity of hydrogen ions surrounding a thin-walled glass bulb at its tip. The probe produces a small voltage (about 0

of an enzyme‚ ’-amylase in starch-iodine solution. We will be testing the relationship between enzymatic reaction affected by temperature and pH. Through the testing the enzyme at different temperatures‚ and different pH levels; it would determine at which temperature and pH level the enzyme worked the most efficiently. Analyzing absorbance of the solutions with spectrophotometery will determine the reaction rate. To test the optimal pH‚ the starch and a buffer were combined at a specific pH level

The decision of a laparoscopic liver surgery or open liver surgery is based on the location and size of the tumor. Laparoscopic (minimally invasive) liver resection can be performed through three of four small keyhole-sized incisions in the abdomen to remove the tumor whether they are benign or malignant. The patient experiences lesser pain and scarring as compared to the traditional open liver resection and can be discharged earlier‚ approximately in two to three days after the procedure. Standard

Investigation on the effects of Temperature‚ pH levels‚ and Enzyme Concentration on the reaction rate of the Decomposition of Hydrogen Peroxide by Catalase The purpose of this investigation is to figure out how temperature‚ pH‚ and enzyme concentration affect the reaction rate of an enzyme. It’s important to understand how certain factors affect enzymes because of their crucial role in the metabolic processes of life. Enzymes lower the activation energy necessary for a chemical reaction to

“Liver transplant ethics: Should alcoholics be sober first? Toronto woman whose husband died in 2010 plans to launch charter challenge”. CBC News. 28 January 2015 This story appeared on the CBC news website‚ some of the questions and points this article raises are: • Should alcoholics be required to abstain from drinking for six months before they are eligible for a liver transplant in Ontario? • Does the six-month abstinence contradict the charter and Canadians’ right to universal access to

Enzyme Catalysis Introduction: Enzymes are produced by living organisms as proteins. These enzymes perform as catalysts to bring about a chemical reaction. In fact‚ most reactions are catalyzed by enzymes during reactions in the cell or in the human body. A catalyst that enzymes pose ad are by definition substances that are capable of initiating or speeding up a chemical reaction. Catalyst are not a necessity during a chemical reaction‚ they are just used to speed up a chemical reaction. This event
